【題目】 English teenagers will take cooking lessons in schools. The idea is to solve the problem that many people are overweight. Also, it worries people that basic cooking and food preparation skills are being lost because parents use too much fast food.

Cooking was once regarded as an important part of education in England-even if it was mainly for girls. In recent years cooking has become less important in schools. But the rising level of obesity (肥胖) has led to a rethink about the food that children are given and the skills they should be taught.

"What we want is to teach young people how to do basic and simple meals, which they can use at home and in their life," said Ed Balls, an education expert. The new lessons will start in September, but some schools without kitchens will be given time to prepare. Also, there may be a shortage of teachers with right skills, since schools teach food technology rather than practical cooking. Besides, the lessons for handson cooking will only be one hour a week for one term. But the well-known cookery writer, Pru Leith, believes it will be worth it. "If we'd done this thirty years ago, we might not lack knowledge about food. Every child should know how to cook, not just that it'll be healthy. But because it's a life skill which is a real pleasure."

The interest in cooking is an effort to reduce the obesity rate, which is almost the highest in Europe. According to the government, half of British people will be obese in 25 years if we don't take measures to prevent it.

【1】完成句子: Basic cooking and food preparation skills are being lost because parents use ____________.

【2】完成句子: Cooking was once regarded as an ____________ in England.

【3】簡略回答問題: How often will the hands-on cooking lessons be given?
